No practice questions?


I downloaded this and it advertises *145 practice questions with explanations* and I cannot seem to access them through the app. Oh well.

Terrible. Don't waste your time or money

John C Wallace

Twenty bucks for a brief description of each arrhythmia with no way to quiz yourself. What am I paying for?

Developer Response

Thank you for the feedback, we appreciate it! We would love to discuss this with you further. Would you mind reaching out to us directly at We typically respond very quickly.

That's it?


Thank Christ they give you a trial for the premium membership. The app is completely lackluster. It gives good explanations on some typical EKGs but with very few examples. It overlooks others such as Brugada syndrome.

Absolutely the biggest problem with the app is the lack of quizzes. There are no options to test yourself on random 12 lead EKGs and at $20, you'd expect thousands of examples. Needs a hell of a lot of work or needs to be completely free.
